Treadmill Motors – This is a very important consideration
AC Motor – Alternating current. Without complicating the explanation too much, AC motors are usually found in Commercial Grade Treadmills. They are more powerful than DC Motors. i.e. a 3hp DC motor, is the equivalent to a 2hp AC motor. AC Motors require little maintenance also. If you require a commercial treadmill, ensure that you purchase a treadmill with at least a 3HP Ac Motore
DC Motor – DC Motors are usually found on home-use grade treadmills. DC motors emit a dust, and therefore need to be cleared of all dust on a continuous basis, otherwise issues may arise. i.e. You will find that the speed sensor will be covered in dust, and your treadmill will not operate at the right speed. Never puchase a treadmill for commercial use that has a DC motor, they are not designed for commercial grade use.
Motor Size Output
Continuous HP (CHP)- This is the output that your treadmill runs at. It is the most important metric. Many suppliers will market the peak HP and ignore the continuous HP. Make sure you always ask what the continuous HP is of a treadmill. You can also check the motor size by opening the treadmill cover. THe motor size will appear on the motor. For a DC Motor, ensure that you purchase a treadmill with at least a 2CHP motor. Motors smaller than that will not last. For an AC Motor, ensure you purchase a treadmill with at least a 3CHP ACmotor. If the treadmill will be used extensively, then a 4 CHP AC motor will be required. Do not skimp on this.
Peak HP – This is the maximum HP that a treadmill motor can run at, which is usually a very short period of time. It is not an accurate measurement of power output of the treadmill. As mentioned many suppliers will advertise this as their continuous HP. Don’t be caught out by this.
Incline – Generally most treadmills will have a maximum incline of 15% which is the norm.
Max Speed – A good home use treadmill will have a minimum maximum speed of 18km/h. Commercial treadmills will have a minimum maximum speed of 20km/h.
Warranty & Maintenance – Different brands have different warranties. No matter how good a treadmill is, it will always need maintenance. Treadmills are like cars, and they take a lot of impact. Ensure that when you purchase the treadmill, the supplier can offer backup service and maintenance on the treadmill
